Tanning bed hygiene: Microbes found on tanning beds present a potential health risk

Tanning bed hygiene: Microbes found on tanning beds present a potential health risk

Foundations and self‐tanning products: Do they provide any protection from the sun?

As soon as the weather turns sunny, everyone wants a tan. People with skin phototypes III and IV, called melanocompetent, have no problem meeting this fashion requirement. But things are quite different for people with phototypes I and II and so these individuals look for alternative solutions. In essence, light skin burns easily when exposed to the sun. Therefore, light-skinned people are offered a cosmetic solution through self-tanning products or foundations. It seemed interesting to us to evaluate the sun protection power of this type of product. To do this, we used an in vitro method to determine the typical indicators related to sunscreen products, such as sun protection factor (SPF), ultraviolet (UV)-A protection factor (PF-UVA), UV-B/UV-A ratio as well as the critical wavelength because these artificial tanning products could be considered sunscreen products by users. It is important to know whether a self-tanning product and/or a foundation provide sun protection and whether they meet the standards set for other sunscreen products. Protection which is imbalanced for either UV-B or UV-A radiation is potentially harmful for users believing themselves adequately protected. To do this, we assembled the requisite conditions for forming melanoidins in the cosmetic itself. We tested seven amino acids found in the corneal cells of the epidermis. Regardless of the amino acid used, the corresponding SPF was essentially zero (approximately SPF 2). Foundations, on the other hand, proved to be much more interesting because they possess a non-negligible SPF as well as good photostability making these products safe in terms of their mode of application (applied once daily).

Behaviors associated with ultraviolet radiation exposure in a cohort of adult survivors of childhood and adolescent cancer

Previous research from the Childhood Cancer Survivor Study (CCSS) has shown that risk of skin cancer is strongly associated with exposure to radiation therapy. The potential role of ultraviolet radiation exposure in survivors has not been described. The CCSS is a retrospective cohort study designed to investigate late effects among 5-year survivors of children and adolescents diagnosed with cancer between 1970-1986. Data regarding current sun protection behavior were collected on 9298 survivors and 2950 sibling controls. Median age at follow-up was 31 years (range, 17-54). In this cohort, childhood cancer survivors and siblings showed similar patterns of sunscreen use (67% vs 66%). Survivors were significantly less likely to report having sunbathed in the previous year (none vs any in previous year: relative risk (RR)=0.92; 95% confidence interval (CI)=0.89-0.95) or use artificial tanning (none vs any in previous year: RR=0.76; 95% CI=0.70-0.83). Compared with survivors without radiation therapy, survivors with radiation exposure showed increased use of sunscreen (RR=1.06; 95% CI=1.03-1.10), and less sunbathing (none vs any in previous year: RR=0.89; 95% CI=0.86-0.92) or artificial tanning (none vs any in previous year: RR=0.62; 95% CI=0.56-0.69). In adjusted multivariable analysis, statistically significant factors for regular sunscreen use in the past summer (vs never/rarely) in the survivor population were being female, having lighter skin complexions, having previously been examined for skin cancer, and having skin that burned when in the sun unprotected. Survivors of childhood cancer self-reported lower tanning practices than siblings. However, because of the potential increased risk of skin cancer from therapy-related exposures, future research should be directed at intervention studies to further reduce UV exposures.

A population-based survey on tanning bed use in Germany

BackgroundThe suntanning industry has grown up over the last decade in Europe, mainly because tanned skin is considered socially desirable and attractive. Because of the potential negative impact of artificial tanning on public health, this study was to investigate tanning bed use behaviour, UV related risk perception and beliefs about tanning in the German population.MethodsIn 2007, a representative telephone survey was carried out among 1501 German residents aged 14 years and older.ResultsMore than one fourth (28%) of the German population have used tanning beds at least once before in their lifetime. High-frequency tanning behaviour, i.e. using tanning beds more than 10 times per year, were recorded for 11%. Men and women aged 18 to 44 years and young women under the age of 18 used tanning beds more frequently (>10 times per year). Tanning bed use was positively related to appearance and lifestyle related beliefs as well as to the perception that tanned skin is healthy.ConclusionThis analysis indicates that tanning bed use is common in Germany. The positive relationships of appearance and health related beliefs with tanning bed use are of great concern. The results indicate underlying misconceptions about the positive effect of artificial UV radiation compared to natural UV radiation particular for high-frequency tanners. The data shows the importance as well as the limitations for risk communication in its current effort to inform effectively about the dangers of artificial UV radiation.

Contact dermatitis caused by sunless tanning treatment with dihydroxyacetone in hairless descendants of Mexican hairless dogs

Dihydroxyacetone (DHAT) is a color additive that is added to sunless tanning products to produce an artificial tan. Although this agent has been used extensively as safe sunless tanning, no published data are available to judge whether the abuse of DHAT causes a potential hazard to the human skin. The purpose of this study was to clarify whether frequent treatment with DHAT solutions had a deleterious effect on the wide skin surface of hairless descendants of Mexican hairless dogs. The skin reactions to the DHAT-treatment were investigated by daily clinical observations and histopathological examinations (21 and 42 days after the beginning of the DHAT-treatment). Clinical observations showed that skin color changes were apparent within 6 h after the first treatment with 5% DHAT solutions, with maximal darkening between 12 and 24 h. Twenty-one days after the beginning of the treatment with 5% DHAT solutions, the skin developed irritant dermatitis, and then the skin lesions gradually became severe during this study. Histopathological examinations showed entire epidermal thickening, 21 days after the beginning of the treatment with 5% DHAT solutions. Forty-two days after the beginning of the treatment with 5% DHAT solutions, the skin exhibited remarkable epidermal degeneration (hyperplastic and dyskeratotic changes) and moderate inflammatory reactions in the dermis. In severe dermatitic sites, I found focal epidermal necrosis or interepidermal blister formation beneath the thickened parakeatotic corneum. Throughout this study, there were no clinical and histopathological changes in the sites treated with vehicle alone. These results revealed that the skin coloring generated by frequent wide treatments with DHAT caused severe contact dermatitis which was associated with the damaged stratum corneum.

Teenagers and Artificial Tanning

Recently, many states have attempted to pass laws to limit teenagers' access to tanning facilities. During the 2007 legislative session alone, 16 states introduced bills on this topic and, as of December 2007, 4 became law.1 At least 28 states and 4 counties regulate tanning facilities for minors.1 Mounting evidence about the carcinogenicity of ultraviolet radiation (UVR) from tanning devices has led to this wave of legislation. Artificial tanning, primarily through of the use of tanning beds in commercial tanning salons, began in the 1970s. The “tanning industry” is booming, with ∼$5 billion of annual revenue, up from $1 billion in 1992.2 Twenty-eight million visits are made to the 50000 tanning facilities in the United States each year.2 Artificial tanning is popular with teenagers. In a national sample of non-Hispanic white teenagers, 24% of respondents between the ages of 13 and 19 reported using a tanning facility at least once in their lives; this represented 2.9 million teenagers.3 In another national survey, 10% of youth between the ages of 11 and 18 reported using indoor tanning sunlamps in the previous year.4 Teenagers are specifically targeted by the tanning industry through methods such as advertisements placed in high school newspapers. Advertisements commonly offer coupons for discounts, including “unlimited tanning” offers.5 Artificial tanning is especially popular with girls and women: of 1 million people who use tanning salons every day, 70% are females between the ages of 16 and 49. Twenty-eight percent of US teenage girls interviewed in 1996 have used tanning salons 3 or more times during their lives.3 Artificial tanning among white girls rises rapidly with age, more than doubling from ages 14 to 15 (7% to 15%), and doubling again at age 17 (35%).6 Of female tanning bed users, at … Address correspondence to Sophie J.

Internet advertising of artificial tanning in Australia

Artificial tanning, defined as deliberate exposure to ultraviolet rays produced by artificial tanning devices, is a new and emerging public health issue in Australia and globally. Epidemiological research suggests that artificial tanning may contribute to the incidence of melanoma, nonmelanoma skin cancer as well as other health problems. Given that Australia has a high incidence of skin cancer, we have undertaken a study to explore how artificial tanning has been promoted to its users. The aim was to analyze the completeness and accuracy of information about artificial tanning. A content analysis of web sites of tanning salons and distributors of tanning equipment in Australia was conducted. A total of 22 web sites were analyzed. None of the solarium operators or distributors of equipment provided full information about the risks of artificial tanning. Fifty-nine percent of web advertisements had no information and 41% provided only partial information regarding the risks of artificial tanning. Pictures with the image of bronze-tanned bodies, predominantly women, were used by all web advertisers. In light of the success of sun-safety campaigns in Australia, the findings of future epidemiological research on the prevalence of artificial tanning and sociological and anthropological research on why people utilize artificial tanning should be a basis for developing effective targeted health promotion on the elimination of artificial tanning in the country.

Use of artificial tanning products among young adults

Neither the prevalence of sunless tanner use nor its impact on sunburning and tanning bed use has been evaluated in the United States. We surveyed young adults in greater Boston to measure use of artificial tanning products, as well as recent history of sunburns and tanning bed use. In July 2004, 448 individuals 18 to 30 years of age completed a brief questionnaire at universities, shopping venues, and parks. Twenty-two percent of respondents used sunless tanning lotions in the preceding 12 months, and another 22% had not used them but would consider doing so in the coming year. Sunless tanning users were more likely to be female, younger, and more likely to report being severe burners. Both users and potential users were more likely to have sunburned during the summer and to have used tanning beds than those who neither used nor intended to use sunless tanning lotions, even after controlling for skin type. The study was based on a non-randomly selected sample in one city and was cross-sectional in nature. Our study raises the possibility that sunless tanning products do not decrease rates of sunburning or use of tanning beds. While safe alternatives to ultraviolet exposure are desirable, the potential risks of widely endorsing artificial tanning products must be considered.

The indoor UV tanning industry: A review of skin cancer risk, health benefit claims, and regulation

Nearly 30 million people tan indoors in the United States annually, including 2.3 million adolescents. Despite increased evidence on the dangers of artificial UV radiation, the popularity of indoor tanning is growing. We aim to assess the following 3 entities: (1) the association of indoor tanning with skin cancer; (2) statements regarding the health benefits of indoor tanning, especially regarding the production of vitamin D; and (3) current regulation of the tanning industry in the United States. We conducted a narrative review of the literature. Indoor tanning poses great risks. Studies support the role of artificial UV radiation in cutaneous carcinogenesis. Despite claims by the tanning industry, artificial tanning is not a safe or necessary way to increase systemic vitamin D levels. The National Institutes of Health and the World Health Organization have acknowledged the risks of indoor tanning. Nonetheless, regulations limiting tanning in the United States are surprisingly sparse. Systematic review of the literature was not performed. Health care providers must increase efforts to warn and educate the public and government about the dangers of UV radiation.

Modulated photoacoustic spectroscopy study of an artificial tanning on human skin induced by dihydroxyacetone

A modulated photoacoustic spectroscopy study on the effect of dihydroxyacetone, commonly used for artificial tan, is presented. The study was carried out in the presence and absence of dimethylisosorbide (a solvent for dihydroxyacetone) on fresh human skin, obtained from the breast region of recent autopsy cases (two females), at a frequency of 25 Hz, which enabled us to study the effect at a depth of 30 µm in the stratum corneum and beneath. By monitoring the photoacoustic signal intensity with time in the region of 300–400 nm, which is a specific region for melanin pigment, it is demonstrated that dihydroxyacetone in combination with dimethylisosorbide enhances the process of tanning. Dihydroxyacetone also has an effect on the amino acids and nucleic acids which is bad for the skin.

To Die For: The Semiotic Seductive Power of the Tanned Body

Human skin burns with prolonged exposure to ultraviolet light. This simple physiological process acquires meaning through social interaction—whereby tanned skin assumes symbolic and semiotic properties. In this article we examine the meanings of tanned skin by focusing on the semiotic seductive power of the tanned body. Drawing from forty qualititative interviews, we examine the motives, beliefs, and experiences of people who tan their skin artificially, that is, through exposure to tanning lamps, in order to understand how tanned skin assumes meaning for them. We analyze the practice of artificial tanning and the interplay among processes of seduction, impression management, self‐expression, and the construction, exchange, and interpretation of embodied sign‐values.

Tanning Salons in U.S. Flout Government Regulation

Artificial tanning, like tobacco, is big business. There are about 50,000 tanning salons in the U.S., and an estimated 5% of the population are regular

Skin color measurements: comparison between three instruments: the Chromameter(R), the DermaSpectrometer(R) and the Mexameter(R).

BACKGROUND/AIMS: Two types of skin reflectance instruments are available nowadays for the determination of skin color: a tristumulus colorimeter (Chromameter from Minolta) using the CIE L*a*b* color system and the narrow-band simple reflectance meters (DermaSpectrometer from Cortex and Mexameter from Courage-Khazaka) using the erythema/melanin indices. The purpose of this study was to compare the capabilities of the three instruments (sensitivity, repeatability and correlation) in vitro and in vivo. METHODS: Comparative color measurements were carried out first in vitro on standardized color charts and subsequently in vivo on different skin areas in human volunteers. Skin color changes induced by various physico-chemical treatments were also quantitatively evaluated with the three instruments. RESULTS: The in vitro and in vivo repeatabilty as well as the sensitivity of the three instruments are rather good. Erythema and skin blanching could be readily quantified by the increase of the a* parameter and of the erythema indices of the simple reflectance meters. Natural UV tanning and artificial chemical tanning could be measured by the decrease of L* and increase of b* and of the melanin indices. CONCLUSION: The Chromameter and the two narrow-band reflectance instruments were able to characterize skin color and to quantify small skin color changes. Moderate to high significant linear correlations could be established between the CIE L*a*b* color parameters and the erythema/melanin indices.

Population UV-dose and skin area--do sunbeds rival the sun?

From the perspective of skin cancer risks, sunbed tanning may give the population group of Swedish adolescents a yearly total dose in terms of ultraviolet radiant energy to the skin which is comparable to sunlight. For populations, a dosage scheme is applied, where exposed skin area is estimated to be two to ten times larger in tanning units than in outdoor sunlight. The normal dose fluence rate is multiplied by the exposure time and by the exposed body surface area. A study of sunbed use among adolescents was reinvestigated. Skin dose from artificial tanning in that population group is calculated and compared to sun exposure for erythemally effective radiation and for UVA (315-400 nm). Skin doses from tanning units to the adolescent population agree with estimates based on information concerning sunbed lamp sales/year. For the population, the erythemal skin dose from tanning units exceeds an increase in solar ultraviolet radiation to the skin projected from 10% ozone depletion. The dosage scheme might help to interpret data suggesting an increased melanoma risk among young people using sunbeds > or = 10 times per year. Tanning and sunburns in sunbeds and in sunlight is discussed with regard to skin area.

Sunbed use in Buenos Aires, Argentina.

The objectives were to survey tanning salons in a defined geographic area of Buenos Aires city and to assess the information offered to consumers regarding chronic exposure to ultraviolet radiation, types of radiation used, and safety measures employed. A prospective study using a standardized interview with limited multiple choice responses for data collection was conducted. Results of the interview survey were that 35% of the establishments (tanning salons) said they used UVA exclusively, 6% UVB, and 25% both; 35% did not know the type of radiation to which their clients were exposed. Sunbeds were promoted as healthy in 56% of the tanning salons, whereas potential risks were mentioned in only 15%. One to 3 sessions on the same day were allowed by 84%, while 40% allowed customers to choose the number of weekly sessions. The use of goggles was optional in 65% of the establishments and 21% did not even provide goggles. Use of sunscreens was not compulsory, and none of the salons had associated physicians. Previous history of skin cancer, sunburn or potential photosensitive drug intake were never recorded, and the age of access was not restricted in 71% of the establishments. In Argentina there are no guidelines to regulate the operation of tanning salon establishments or the equipment they use, and there are no specific measures taken to prevent skin and ocular pathologies. Ways to reduce the risks of ocular and skin pathologies from artificial tanning in Argentina are urgently needed.

A population-based survey on the use of artificial tanning devices in the Province of Québec, Canada

Background: The suntanning industry has grown up over the last decade in North America, mainly because tanned skin is socially desirable and artificial tanning is perceived as a “safe tan.” However, exposure to UV radiation is known to cause adverse health effects. Objective: The purpose of this study was to estimate the prevalence of use of tanning equipment in the Province of Québec and to characterize people who reported using these devices. Methods: In 1996, a telephone survey was carried out among adults from the two most densely populated regions (Montréal, Québec) of the Province of Québec. The final sample included 1003 white persons 18 to 60 years old. Interviewers used a standardized questionnaire to document the characteristics of the participant, skin phototype, and exposure habits to artificial UV radiation sources. Results: During the last 5 years before the survey, 20.2% of the respondents reported they had used, at least once, a tanning device in a commercial tanning salon. The rate of use during the last 12 months before the study was 11.1%. A significantly higher proportion of female, young people (18 to 34 years old) and single persons was found among tanning bed users. Twenty-six percent of users experienced one or more acute adverse health effects from the artificial UV irradiation. Most of these were cases of skin burns. A high proportion (77.5%) of those who used tanning equipment during the last year before the study said they would return to tanning salons. The intention of returning to a tanning salon was not influenced by the occurrence of the acute adverse health effects. The most prevalent reason given for using tanning equipment was “to improve their appearance by a tan.” Most people (60.4%) who used a tanning bed during the last 5 years before the study believe that tanning salons are not dangerous. Conclusion: This survey indicates that tanning bed use is very prevalent in the Province of Québec, mainly among young women. The high rate of acute adverse health effects related to artificial tanning, particularly skin burns, is of concern. Finally, our results underline the importance of changing attitudes and beliefs in the population regarding artificial tanning. (J Am Acad Dermatol 1999;40:572-6.)

Natural and artificial tanning

Although sunlight is beneficial to provide light and warmth and aids the body in the formation of vitamin D, tanning is potentially damaging to an individual's health. The incidence of skin cancer and retinal damage from both natural and artificial light is on the rise. This article explores the concept of tanning, types of ultraviolet rays and related health hazards. Health care provider interventions for prevention and client education are also emphasized.

Safety Information Provided to Customers of New York City Suntanning Salons

Little is known about the safety information tanning salon operators provide to customers or the extent to which artificial tanning salons adhere to federal regulations designed to protect customers from excessive ultraviolet radiation (UVR) exposure. We surveyed the operators of 20 artificial tanning salons in New York City from 1988 to 1989 concerning salon operating procedures and information provided to potential customers. Results revealed a disparity between known health risks of UVR exposure and safety information provided to tanning salon customers. For example, 75% of salon operators informed potential customers that artificial tanning would not cause a sunburn, and 80% informed potential customers that they would not get skin cancer from artificial tanning. Artificial tanning salons are a rapidly growing industry in the United States, with over two million customers annually. Results from this survey indicate a need for greater regulation of the tanning salon industry and for education of tanning salon operators in the risks associated with the use of artificial tanning devices.

Skin tanning and light protection-theory, agents and analytic aspects. 1. Skin tanning and skin tanning agents

The different approaches to achieving skin tanning with emphasis on natural tanning, due to UV radiation of the sun or solaria, and artificial tanning through tannings agents are described. In contrast to the artificial tan the natural tan is a protection against UV radiation and is caused by pigmentation (melanin formation). The artificial tanning is based on a chemical reaction usually by means of dihydroxy acetone (melanoidin formation). Reaction mechanisms by both agents are reported. The determination of dihydroxy acetone in cosmetic tanning preparations by TLC, GC, HPLC, enzymatic tests and by a new method for capillary GC including sample preparation is described. When exceeding the natural protection mechanisms the skin should be protected by physico-chemical measures. The active principles in sunscreens are the UV filtering substances. UV filters permitted in the EG are listed. 2-Hydroxy benzophenone is used as an example to explain the mechanism of UV filtering substances. Analysis of UV filtering substances in cosmetic sunscreens by TLC, GC, HPLC is described as well as a fast and simple method for separation of lipophilic UV filters followed by capillary GC determination.

The use of dihydroxyacetone for skin tanning.

Within the past year a number of similar cosmetic preparations have appeared on the market and have been extensively advertised for their tanning effect on the skin. In our practices we have received numerous inquiries regarding their effectiveness and safety. There seems to be a general impression on the part of the laity that the artificial tan which these agents produce will protect against sunlight. This investigation was undertaken to determine the possible sun-screening properties and effect upon melanogenesis of dihydroxyacetone, the active ingredient in these preparations. Experiment I Ten healthy white male volunteers were used. Three test areas, each measuring 1×1 inch (2.5×2.5 cm.), were marked out on the external aspect of one arm of each subject. Dihydroxyacetone lotion * was applied to one of these test sites. Twenty-four hours later this site was given a 4+ erythema dose of ultraviolet light produced by Westinghouse FS4OT-12 fluorescent ultraviolet lamp. The
